Storage bag for breast pump

ABSTRACT

The disclosure regards a storage bag for breast milk or other liquids or materials. The storage bag includes first and second closures, wherein a first line of perforations is U-shaped and extends through the first closure, thereby allowing an output of a breast pump or other device to be inserted through the area where material defined by the first line of perforations is removed. The first closure can further be used to engage the output of the breast pump or other device. A second closure is formed further within the storage bag and defines a storage volume. A second line of perforations is provided above the second closure. After the storage volume is filled, the second closure can be closed and the material above the second line of perforations can be removed.

BACKGROUND OF THE DISCLOSURE

This application claims priority under 35 U.S.C. §119(e) of provisional patent application Ser. No. 61/307,752, filed on Feb. 24, 2010, the contents of which are hereby incorporated by reference in their entirety.

1. Field of the Disclosure

The present disclosure relates to a storage bag which is adaptable to a breast pump and further adaptable to the storage of breast milk, as well as being adaptable to serving as the bag for a baby bottle. The present disclosure may be applied to other liquids.

2. Description of the Prior Art

The advantages of breast-feeding are well-established. Similarly, the use of breast pumps is well-known to allow the mother who may be away from home, such as a working mother, to collect the breast milk for consumption by the baby. However, this typically requires the mother to transfer the breast milk between various containers, which may result in the spilling or contamination of the breast milk. Additionally, the use of several containers requires that these containers be kept meticulously clean.

SUMMARY AND OBJECTS OF THE DISCLOSURE

It is therefore an object of the present disclosure to allow the use of a breast pump while reducing the number of containers to which the breast milk must be transferred, thereby reducing the chances of spilling or contamination of the breast milk.

This and other objects are attained by providing a storage bag which is can receive the breast milk from the breast pump, store the breast milk, and provide a pour spout for pouring the breast milk into a baby bottle. Alternatively, the storage bag can be inserted directly into a baby bottle.

The bag includes a first closure (preferably adhesive, but may also be a zipper) with a first U-shaped perforation which extends therethrough, and further includes a second closure (preferably a zipper, but may also be adhesive) with a crescent-shaped perforation thereover. The material within the first U-shaped perforation is removed in order to attach the storage bag to a breast pump. After the breast milk has been accumulated, the portion above the second perforation is removed and the second closure is closed. The milk can then be stored or transported. When it is time to use the milk, the second closure is opened and either the milk is poured into a baby bottle or the storage bag is inserted directly into a bottomless baby bottle and the crescent shape acts as pull tabs to pull over the bottle. The top cap of the bottle with the nipple is then screwed down to capture the tabs between the inside of the cap and the outside of the bottle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, one sees that FIG. 1 is a plan view of the storage bag 10 of the present disclosure. Storage bag 10 is typically made of polymeric material and is typically sterilized to maintain the safety of the breast milk. Storage bag 10 includes front and rear walls 12, 14 with a closed bottom such as a bottom seal 16, and first and second side seals 18, 20, wherein some embodiments may replace one of the seals with a fold. Alternatively, the storage bag 10 may be provided in a cylindrical tube and a bottom seal 16 thereby eliminating the side seals 18, 20 and further improving its compatibility with a cylindrical baby bottle 300 (see FIG. 4). A mouth 22 is formed at the top edge 24. First closure 26 is placed in the interior of storage bag 10, just below mouth 22, thereby providing a closing device for mouth 22. First closure 26 is preferably an adhesive such as one approved for direct food contact such as, but not limited to, Aqua Tack 320 from Aqua Based Technologies, a division of ADM Tronics Inc. Further the term “adhesive” may be construed to include a substantially chemical-free surface treatment which provides adhesion such as the “Dry Adhesive” product by Nano Terra. Moreover, first closure 26 may further be a zipper such as shown in FIG. 5.

A first line perforations 28 has a U-shape, starting at the top edge 24 of both front and rear walls 12, 14 (or on both the front and rear of the tube, if storage bag 10 is provided in a tubular shape) and extending through a central portion of first closure 26, so that a U-shaped portion of material 30 (including a central portion of first closure 26) is defined by first line of perforations 28.

A second closure 34 (typically a zipper as shown in FIG. 5, but may be an adhesive as described above with respect to first closure 26) is placed across the interior of the storage bag 10, typically somewhat above the vertical mid-point of the storage bag 10 thereby defining a breast milk storage volume 100 therebelow. A labeling portion 36 is provided on front wall 12, just above second closure 34, so that the user can label the storage bag 10, typically recording such information as the date and time that the storage bag 10 was filled. A second line of perforations 38 is placed across the front and rear walls 12, 14 of storage bag, immediately above the labeling portion 36. The second line of perforations 38 is typically has an upwardly arcing or crescent shape in order either to provide a pour spout or to provide pull tabs for use with a bottomless baby bottle 300 (see FIG. 4). The first and second lines of perforations 28, 38 can be replaced by other lines of weakness, such as laser scored lines, etc.

The typical structure of zippers, typically made of polymeric material, which may be used as first and second closures 26, 34, is shown in FIG. 5. Particularly with respect to second closure 34, it is imperative that the zippers are highly liquid-resistant as well as providing a very tight seal against any possible contamination. First double zipper profile 50 is attached to front wall 12 and includes first male interlocking element 52 and first female interlocking element 54. Second double zipper profile 60 is attached to rear wall 14 and includes second female interlocking element 62 and second male interlocking element 64. First and second male interlocking elements 52, 64 are typically arrowhead shaped, which are tightly engaged by detent hooked arms 70, 72 of second female interlocking element 62 and detent hooked arms 66, 68 of first female interlocking element 54, respectively. Additionally, first and second female interlocking elements 54, 62 include first and second laterally extending barrier projections 74, 76 which increase the liquid resistance and contamination resistance of the closures 26, 34, when implemented as zippers. Typically, at least one of the projections 74, 76 of second closure 34 (when implemented as a zipper) will be visible, thereby confirming to the user that the second closure 34 is properly closed or interlocked.

The sequence of using the storage bag 10 is shown in FIGS. 2-4. As shown in FIG. 2, first line of perforations 28 is torn so as to remove U-shaped portion of material 30. Second closure 34 is disengaged. The output 200 (shown in phantom) of breast milk pump is placed within the storage bag 10 through the port 30′ where U-shaped portion of material 30 (FIG. 1) was removed. The output 200 of breast milk pump may inserted as far as storage volume 100. Additionally, first closure 26 may be engaged around output 200 to temporarily secure the output 200 to the storage bag 10 (an embodiment with adhesive as the first closure 26 is well-adapted to this engagement), so that the storage bag 10 is prevented from falling off when filled with milk while second closure 34 is open. Once the operation of the breast milk pump is completed, the user withdraws output 200 from storage bag 10, closes second closure 34 and tears along second line of perforations 38 to achieve the configuration shown in FIG. 3. Some users may prefer to tear along second line of perforations 38 prior to closing second closure 34. With the configuration of FIG. 3 (with second closure 34 closed), the storage bag 10 may be transported or stored. When it is time to use the stored milk, the user may open second closure 34 and pour the milk into another container, using the crescent shape provided by second line of perforations 38 as a pour spout. Alternatively, the milk may remain in the storage bag 10, the storage bag 10 inserted into a baby bottle 300 (see FIG. 4, typically a bottomless baby bottle) and the crescent shape provided by second line of perforations 38 will provide pull tabs for the user to pull a portion of the walls of the storage bag over the bottle. The top cap 302, including nipple 304, is then screwed down to capture the pull tabs between the inside of the top cap 302 and outside of the bottle 300.

This disclosure is not limited to the storage of breast milk and may be used for storage and transportation of other fluids or even powdered or granular material.
